6 Claims. c1. 229 s1 Thisinvention relates to improvements in boxes or cartons and particularly to improvements in hollow wall boxes or cartons. I

Broadly, hollow wall boxes or cartons are those in which there is provided opposed side and end walls each of spaced apart inner and outer wall members with two opposed walls each having its inner wall member hingedly connected to the bottom or base of the carton and with the remaining wall members having its inner wall member folded to depend within the carton and be locked in operative position.

By the present invention there is'provided a box or carton of the general characteristics as heretofore known but in which the end walls each have its wall members substantially automatically spaced from one another and reinforced to provide the carton or box as a whole with considerably greater strength and rigidity than heretofore known.

7 It is the principal objects of the present invention to provide a carton or box with end walls each of which is provided with spaced apart inner and outer wall members and in which the said wall members are substantially automatically spaced upon erection.

Another object of this invention is the provision of a box or carton of the hollow or spaced apart walls variety in which the end walls, two opposed walls, have their wall members transversely braced at the upper and lower ends thereof.

A further object of this invention is the provision of 'a box or carton that will accomplish the foregoing object and have its said end walls, two opposed walls, braced transversely of its height.

A still further object of this invention is the provision of a single blank from which a knocked-down carton may be erected to accomplish the foregoing objects.

It is a still further object of the present invention to provide a box or carton for accomplishing the foregoing objects that is economical to produce and acquire.

Other objects and advantages of the present invention should be readily apparent by reference to the following condition and certain parts removed for the simplicity and clearness in illustration.

Fig. 14 is a fragmentary sectional view through an end wall of Fig. 11 as seen from line 1414 on Fig. 12.

Throughout the several views of the-drawings similar reference characters are employed to denote the same or similar parts.

Two modifications of the invention are illustrated i'n the drawings and they will be described in detail with each modification incorporating the principles of the present invention, and which modifications are to be regarded as examples only and in no wise restricted as to the only methods of incorporating the invention.

Specifically the blank of Fig. 1 comprises a base or bottom 15 bounded by score or fold lines 16, 17, 18 and 19 with said score or fold lines 17 and 19 regarded as the sides while the score or fold lines 16 and 18 may be regarded as ends. The side score or fold lines 17 and 19 eachhingedly connects with the base 15 a similar extension 20 and 21 which in the erected carton form the side walls as will presently be made clear. The end scores 16 and 18 similarly hingedly connect with the base 15 substantially identical extensions 22 and 23 which in the erected carton form the end walls.

Since the side wall extensions 20 and 21 are substantially identical it is deemed sufficient if but one of them be described in detail. Accordingly, extension 21' is provided longitudinally thereof between the base attaching score or fold line 19 and its outer edge with parallel score or fold lines 24, 25 and 26 thereby providing in said extension, panels 27, 28, 29 and 30. In the erected carton the panel 27 forms the side wall outer wall member and has its ends defined by score or fold lines 31 and 32 which are in substantial alignment with the base end scores 16 and 18. The panel 28 in the erected carton forms theside wall top wall member and is of a length substantially equal to the length of the carton bottom 15 and has its ends provided by cut lines. The panel 29 forms the side wall inner wall member having its ends defined by score or fold lines 33 and 34. The score or fold lines 33 and 34 integrally hingedly connect with the panel 29 tucking flaps 35 and 36 adapted, in the erected carton, to extend transversely of the carton base or bottom 15.

In addition the panel 29 is provided inwardly of its ends with elongated apertures 37 and 38 which cooperate with locking lugs, as will presently be made clear, on the end wall extensions for securing the carton walls in their final and fully erected positions. The remaining panel 30 Patented Nov. 18, 1958 constitutes a glue flap for securing the lower end of the inner wall member or panel 29 to the base 15, and for wghich purpose the said panel 30 is provided with adhesive 3 L The end wall forming extensions, similar to the side wall forming extensions, being substantially duplicates of one another it is deemed sulficient if but one of them be described in detail.

Accordingly, extension 23 between the attaching base score or fold line 16 and outer end thereof is provided with a plurality of parallel score of fold lines 40, 41, 42, 43, 44 and 45 forming in said extension panels 46, 47,

48, 49, 50, 51 and 52. In the erected carton the panel .46 forms the end wall outer Wall member having its ends defined by score or fold lines 53.and 54 which are in substantial alignment with the base side score or fold lines fold lines 53 and 54 respectively hingedly connect therei ;with the adjacent edge of a corner piece or fiap 55 and 56. The said corner nieces have their right angle edge defined .by the side wall outer wall member end score or fold .lines 31 and 32 through which the said corner pieces are integrally hingedly connected to said side wall outer wall member on panel 27. The corner pieces 55 and 56 are each rovided with a diagonal score or fold line 57 through which said corner pieces are, respectively, folded on them- ,quently referred to as bellows corners.

In the erected carton the end wall extension panel 47 forms the end wall top wall member, while the panel 48 forms the normal or exposed end wall inner wall member.

The end wall inner wall member 48, in the erected carton,

-wall member 48 has its ends, for the major portion there- .of, defined by score or fold lines 59 and 60 which hingedly ,connect the opposite ends thereof to spacing flaps 61 and 62 for spacing the vertical edges of the end walls inner and outer wall members from one another. In addition the end wall inner wall member or panel 48 beyond its .score or fold lines 59 and 60 has projecting therefrom locking lugs 63 and 64. a

In the erected carton the panel 49 of the end wall extension forms an end wall bottom wall member while the panel 50 forms a vertical spacing member and the panel 51 .forms an end wall inner top wall member and reinforcement. The said panels or wall members 49, 50 and 51 are each of a length of the effective length of the end wall inner wall member 48. The remaining panel 52 of the extension 23 constitutes a glue flap for securing the end .wall'reinforcing panels in operative position and for which purpose it is provided with adhesive 65.

After the blank is cut and scored as illustrated in Fig.

l and the adhesive 39 and 65 applied to their respective glue flaps the extensions 21 and 22 are folded to the position illustrated for that of extension 20 in Fig. 1. This folding being efiected on the score or fold line 24 of .each extension for thereby superimposing the panels 28,

29 and 30 of each extension on its panel 27 and on the base 15 and securing the glue flaps 30 to said base.

The end walls extensions 22 and 23 are then folded as illustrated in Fig. 2, namely, each end wall extension .has its glue flap 52 first folded onto the panels 51 and 50 for thereby exposing the adhesive 65 of each glue flap 52. The end walls extensions are then further folded each on its score or fold line 42 to bring its glue flap and adhesive into engagement with the panel 48. Pressure is 'then applied to effect an adequate securing of all glue flaps in position which results in the blank, as illustrated selves, bellowswise, wherefore said corner pieces are frein Figs. 2 and 3, being knocked-down and is then ready to be shipped to the user in this condition.

The user upon desiring to set up the box or carton does so by raising the folded or knocked-down side walls to upstand from the base or bottom. The raising of the folded side walls automatically disposes the inner and outer wall members thereof to be normal to said base or bottom with the top walls members parallel therewith as illustrated in Fig. 4. a

The end walls may now have the reinforcing members thereof raised to the positions such as illustrated at 66, in phantom lines, in Fig. 2, or the said end wall reinforcing members allowed to remain in their flat position to be positioned just prior to the locking of the end walls in position. At this time the tucking fiaps 35 and 36, at one end of the carton, are positioned to extend transversely thereof, as illustrated for one of said tucking flaps at the lower end in Fig. 4. The end wall extension, at the said one end of the carton, is now raised or folded on its score or fold line 16 and simultaneously thebellows corner pieces 55 and 56 are folded on themselves on the diagonal score or fold lines 57 and disposed transversely of the base or bottom 15 whereupon the said end wall outer wall member 46 is vertically of the said carton base or bottom 15. The said end wall extension is now folded to dispose the end wall top wall member 47 parallel with the carton bottom or basewith the contoured ends thereof lying on the side walls top wall members. The inner wall member is now folded to depend within the said carton. Prior to the downward positioning of the carton end wall inner wall member the spacing flaps 61 and 62 are folded to project toward the end wall outer wall member. Simultaneously with the downward positioning of the end wall inner wall member the end wall reinforcing members are positioned as illustrated in Fig. 4, which reinforcing members form, in effect, substantially a tube, and the said inner wall member is folded to its operative position until the locking lugs 63 and 64 snap into the elongated locking apertures 37 and 38 of the side wall inner wall members for completing the erection of one end wall.

The end wall extension at the other end of the carton is now erected in the same manner as just described. The carton is now in its fully erected position as illustrated in Figs. 5, 6 and 7.

It will be noted from Figs. 5 and 7 that the end walls inner and outer wall members are braced against displacement by the bottom walls or panels 47 and the top wall inner wall member 51 and that said parts-are retained in their braced positions by the end walls glue flaps 52. By reference to Fig. 7 it will be noted that the said end wall bottom wall member 49 and top wall inner member 51 extend the full length of the said end walls. As most clearly illustrated in Fig. 5 the tucking flaps 35 and 36 and the bellows corners 55 and 56 are disposed between the end wall outer wall member and the vertical brace or panel 50 thereby providing a structure which is amply reinforced to withstand pressures under which structures as heretofore known would collapse. It will further be noted that the shifting of the end wall inner wall member to its operative position substantially automatically arranged the reinforcing members to their operative positions, since, as the bottom of the said inner wall member 48 engaged with the carton base or bottom panel 15 the bottom wall member 49 was forced thereby to become parallel with the said carton bottom or base and through its hinge connection with the end wall top wall inner member forced the remaining reinforcing members to assume their operative positions as illustrated in Fig. 5.

In the modified carton illustrated in Figs. 8 to 14, inclusive, the chief change is in providing the end wall with an additional brace intermediate the said end walls bottom wall members and top wall inner members. The said intermediate brace is cut or formed from the reinsame forcing panels or members and glued in operative position to the end wall inner wall member.

Specifically and as shown in Fig. 8 this intermediate brace is provided by forming within the end wall bottom wall member or panel 49" and within the end wall vertical brace or panel 50, a panel 67 shown in the drawings as somewhat T-shaped with a stem portion 68 formed within the panel 49' and a lateral or arm portion 69 formed in the panel 50. The stem portion 68 has its sides defined by cut lines 70 and 71 while the arm portion 59 has each of its ends defined by angular cut lines for providing the arm portion with substantially diamond shaped ends 72 and 73. The arm portion 69 has the points of its ends 72 and 73 joined by a score or fold line 74. The panel 67 in its entirety has its one end defined by the score or fold line 42 and its other end defined by a score or fold line 75 wholly within the Pan l The only purpose for the panel 67 being shown as T- shaped, in plan, and with the ends of its arms diamond shaped is to obtain a maximum length of transverse brace with a minimum of weakening in the reinforcing end wall panels 49' and 50.

In order to insure the proper adhesion of the parts the .end wall extensions 22' and 23' each have their glue flaps 52 modified to the extent of having a relatively narrow lug 76 projecting from the free ends thereof.

A further modification in the blank of Fig. 8 over that of Fig. 1 is the changing of the glue flap 30 of the side wall extensions 20 and 21 to a bottom wall member 30' and integrally hingedly connecting therewith through a score or fold line 77 the glue flap 78. The purpose for this modification is to secure the lower ends of the side walls inner wall members, through the side walls bottom wall members, to the inner surfaces of the side walls outer wall members.

After the blank of Fig. 8 has been cut and scored the side wall extensions have adhesive 79 applied to the undersurface of its glue flaps as seen in Fig. 8 whereupon said extensions are folded on their score or fold line 26 n and then said extensions refolded on their score or fold lines 24 for thereby bringing said extensions to their knocked-down positions as illustrated by the upper end of said Fig. 8.

Adhesive 80 is now applied to the end wall extensions lugs 76 whereupon the said end wall extensions are folded on their score or fold lines 44. Adhesive may now be applied to the exposed portion of the glue flap 52, or spot gluing or adhesive 81 applied to the end wall extensions inner wall members or panels 48; this being illustrated in Fig. 8. The end wall extensions are now further folded on their score or fold lines 42 to bring them into the position illustrated for end wall extension 22' in Fig. 8. The said blank is now in its knockeddown position as illustrated in Figs. 9 and 10 for shipment to the user.

The user in desiring to erect a cart-on from the modified blank of Fig. 8 follows the same erecting procedure above set forth for the knocked-down blank of Figs. 2 and 3. The resulting carton has substantially the same appearance as that of the blank of Fig. l, as will be readily apparent by a comparison of Figs. 4 and 11. The chief distinction in the appearance of the cartons is the absence from Fig. 11 of the glue flaps 30 of Fig. 4 which extend toward one another inwardly of the carton.

The structural distinctions between the cartons is illustrated in Figs. 5, 7, 12 and 14 wherein it will be noted that the end walls are transversely braced intermediate the top and bottom bracing thereof. The said intermediate bracing is indicated at 82 and is the portion of the panel 67 located between the score or fold lines 74 and 75. It will further be noted that the said end walls of the modified structure are amply laterally braced by the bottom wall or panel 49 on each side of the T-shaped panel stem portion 68.

From the foregoing it is believed now evident that there has been provided a blank for forming 'a box or carton which accomplishes the objects initially set forth.
